Here's what the Kook's catted mid-pipe looks like .. other are similar .. Kooks Long Tube Headers- 1 5/8"x 2 1/2" w/Catted H-Pipe- 2005-2010 Ford Mustang GT (4.6L V8)
As far headers go .. basically comes down to how much do you want to spend?
JBA headers with a catted h-pipe is about the cheapest @$900-ish.
Headers 6675S, $470, Mid Pipe 6675SHC &430, JBA makes their headers out of 409 stainless, so they're a little cheaper than headers made out of 304.
409 SS is OEM grade and should last the life of your car, but it can rot out under harsh conditions..
Kook's are made out of 304 and run 1200-ish ..
Pypes makes a Chinese knock-off of the Kook's for 900-ish with their high flow cats.
American Racing Headers make a nice header 1400-ish ...
Other brands, BBK, SLP, Bassani, Stainless Works make stainless headers,
Pacesetter, Hooker, BBK and MAC make mild steel headers, Since you're in NJ, you'll want to go with stainless as the mild steel will definitely rot out ..
Also, I though NJ has a rather tough emissions test so you'll need to talk to somebody in NJ that has passed emissions and see who tuned their car.
